Calming the Flow
When it comes to maintaining pressure in municipal water systems, consistency is the name of the game. Pressure transients can have a serious impact on both service quality and asset life. The challenge is determining if transients are taking place and pinpointing their source in a timely manner to mitigate the destructive effects. That was the situation facing the East Valley Water District (EVWD), which provides water and wastewater services to 103,000 residents of California’s San Bernardino County. Pressure transients, aging assets, bedding failures and corrosion are all potentially contributing factors to observed line breaks.
